JOU RNAL-BOX. PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 421,610, dated February18, 1890. Application filed November 15, 1889. Serial No. 330,459. (Nomodel.)

To all whom it may concern.-

Be it known that I, HENRY S. PU GSLEY, a citizen of the United States,residing at Oakland, Alameda county, State of California, have inventedan Improvement in J ournal- Box Protectors; and I hereby declare thefol-,

4 tect the inner end of the box as to prevent the oil or grease fromescaping and the dust from entering.

Referring to the accompanying drawings for a more complete'explanationof myinvention, Figure 1 is a vertical longitudinal section of ajournal-box, showing the application of my invention to its pocket 0.Fig. 2 is a perspective view of my protector, the parts being shownseparated.

A is an axle-box of a well-known pattern, having in its top the usualbearing a for the journal I) of the axle B. The boxAis cast at its innerend, so as to form an open-topped pocket 0, having through it the oblonghole or aperture, through which the axle passes. It is customary toinsert in this pocket a plate of wood, having a hole through it for theaxle, said plate being for the purpose of keeping the grease in andpreventing the entrance of dust, objects, however, which it effects butpoorly. My invention dispenses with this ordinary plate and substitutestherefor a protector which accomplishes the desired objects moresatisfactorily.

D are two similar plates of any suitable material,each of the plateshaving side flanges d, which are beveled or inclined in oppositedirections--that is to say, the flanges of one plate incline in thedirection opposite to the flanges of the other plate-so that when thetwo plates oppose each other the beveled flanges act as reverse wedgesto tighten and hold both plates in place. Each of these plates isprovided with an oblong hole 61, which corresponds to the oblong holethrough the pocket 0 at the inner end of the box. The plates D arefitted in this pocket as follows: Before the axle is inserted one of theplates is set down in the pocket against one of its walls. The otherplate is then set in the pocket against the other wall, and on accountof its oppositely-inclined flanges coming in contact with the flanges ofthe first plate the two plates, when adjusted fully to place in thepocket, are forced apart by each other, so that each plate is pressedtightly against the wall ofthe pocket, making a tight joint, and alsoagainst the end walls of the pocket, thus making a perfectly tight jointall around. They also provide for a smooth inner surface, in which theblocks, now to be described, are seated. These blocks, which arerepresented by E and E, are of any suitable material, and are made incorresponding halves or two parts, each provided with a semicirculargroove, forming, when the blocks come together, acircular hole 6,through which the axle passes. The upper block E encircles the upperportion of the axle, and the lower block E encircles the lower portionof the axle, and the joint or line of separation between the two iscovered by a tongue 6 in the lower block, fitting in the groove 6 in.the upper block, so that the space between the two blocks is keptconstantly closed, and yet the plates may have their necessaryindependent play. The lower block is heldto its seat on the axle by aspring F in the bottom of the pocket O, and the upper block may have asimilar spring or may be held to place by its own weight. These blocksfit just snugly enough between the bearingplatesD to provide for theirnecessary sliding movement.

It will be seen from this construction that a sufliciently tight jointis formed between all the parts, which will prevent the grease fromescaping and will prevent the dust from entering. Only a small portionofthe grease will find its way along the axle, itself sufficient tolubricate the bearings of the encircling block E and E.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In combination with the journal-box having at its inner end a pocket0, the apertured bearing plates D, fitted in said pocket against itswalls, and having oppositely-inelined side flanges, whereby said plateswedge themselves in place and make a tight joint with the walls of thepocket, and the independent movable blocks E and E, fitted between theplates in the pocket and encircling the axle, substantially as hereindescribed.

2. In combination With the j ournal-box having the pocket 0 at it itsinner end, the apertnred bearing-plates D, fitted in the pocket, andhaving oppositely-inclined side.

flanges, whereby said plates wedge themselves in the pocket and formtight joints against its Walls, the independent movable blocks EE',fitted between the plates D in the pocket and encircling the axle, andthe tongue in one block and groove in the other, whereby theirline ofseparation is kept closed, substantially as herein described.

3. In combination with a journal-box hav ing a pocket at its inner end,a protector therefor, consisting of the apertured bearingplates D,having oppositely-inclined side flanges, whereby said plates wedgethemselves against the walls of the pocket and form tight jointstherewith, the independent movable blocks E E, fitted in the pocketbetween the plates D and encircling the axle, the tongue and groove ortelescopic connection between the blocks, whereby their line ofseparation is kept closed, and the spring F in the bottom oL' the pocketfor holding the lower block up to the axle, substantially as hereindescribed.

In witness whereof I have hereunto set my hand.

HENRY PUGSLEY.
